They were able to operate alone or with a pilot, either way mattered not to these ancient beasts. They commanded thousands of troops and watched entire systems burn. It is said that some of them were forged in the death of countless worlds, but none can prove it today. They are rumors, ghost stories even, that the beast mecha tell each other during down time from missions. They had identifying marks of course such as multiple Harmonic Disruptors beyond the standard two we see them equipped with today. They also had the Skraig primary weapon of the Ursa Strike embedded in their central core, and were built with customization in mind being proficient with any weapon they cared to install on themselves. In short they were the ultimate beast machine.
No one knows where they may be hiding if in fact any exist today, speculation points towards the Forerunners taking these living engines of destruction with them when they departed from this galaxy. Questioning of the Nakshi we know today reveals nothing, likewise with Skraig, and Gigus. They exist as a story for now within the circles of the living machines we pilot today. Take heed however for any living mechas tales of a bogeyman should be taken most seriously especially for the races of man who may one day accidently stumble across these ancient and powerful creatures. Then only the powers above may save us from these living engines of destruction.
